INCANDESCENI GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 700,574, dated May 2 0, 1902.

' Application filed March 19, 1902. Serial No. 99.001. (No model.)

To LZZ whom it may concern:

Be it known that I, CLARENCE W.'lAYLoR,a citizen of the United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented new and usefulImprove-` ments in Incandescent Gas-Burners, of which the following is a specification.

This invention relates to certain new and usefulimprovementsinincandescentgasfbur-v ners; and the object thereofis toconstructa burner of this class in which the gasY con sumption, the incandescence of the mantle,

ment of parts hereinafter more specifically. defl scribed,illustrated i n the accompanying draw-- ings, and particularly pointed out inftlle;

claims hereunto appended.

In describing the linvention in detail refer'A ence is hadgto the accompanying drawings, forming a part of this specification, wherein like numerals ot reference indicate correspondingparts throughout the several views,

and in which- Figure l is a' vertical central sectional View of my improved burner, showing the chimney, globe, and gallery in dotted lines.

Referring to the drawings by r`eference-nu-,- merals, l denotes a gas-supply pipe, to which;-

is secured in any suitable manner the nipple 2, formed with an annular peripheral flange 3 near the bottom thereof and an annular peripheral'shoulder 4 approximately centrally thereof. The top of the nipple 2 has-secured Fig. 2 Vis a plan view of the nipple with the gasregu-f Y thereto in any suitable manner a diaphragm 5, provided with perforations or slots 6 for thepassageof gasfrom the source of supply through the nipple 2 to the burner-tube 7, the latter' being of the ordinary Bunsen type, and

which Yhas its lower end surrounding the up 4per portion of the nipple 2 and resting upon the shoulder tof the latter. The tube 7 issecured to the nipple 2in any suitable manuel'. The burner-tube 7 above the nipple 2 is provided with4 the usual air-inlets 8 and further provided below the inlets 8 with a slot 9 to permit of the operation of the gas-regulating plate, to be hereinafter referred to.

Mounted upon the top of the nipple 2 and .within the burner-tube 7 below the air-inlets 8 is afga's-regulatiug plate l0, provided with a suitable opening or openings l1, adapted to register with the openingsor'slots 6 in the diaphragm 5. The opening or openings 11 in 'the plate l0 is or are so arranged that one or more or all of the openings or slots 6 will be opened or closed when the plate 10 is rotated upon-the nipple 2 toV bring lthe opening or openings 1l into or out of alinementwith the openings or slots 6, therebyregulating the 4supply-of gas to the jburner.v The plate 10 may beA constructed withoutthe opening or 1 openings, but of such shape that when rotated it will cause the opening orclosing of one or more or all of the openings orslots 6 in the diaphragm 5. A construction of'plate as referred to is shown in Fig. 2. By the adaptation of the plate in the manner set forth it will be obvious that the passage of gas can be suitably regulated atwillfrom tl1e gassupply 'to the burner. The vplatelO isconstructed with an outwardly-projecting stud 12, which extends through the slot 9 in the burner-tube 7 The stud l2 is provided s othatthe plate lO can be rotated toregulate the passage of gas through the diaphragm,` as before stated.

The reference-numeral ldenotes an enlarged upper portion of the gas andair` mixing tube and which formsuthe gas land air mixing chamber 1 4. The top of the enlarged portion 13 has mounted thereonl a foraminous diaphragm 15, whichprojects over the edges thereof and carries a heat-radiator l5 of any preferred form of construction,which depends downwardly into the chamber 14.

The reference-numeral 16 denotes the lower IOO portion of thegasl and air mixing tube and is of much less diameter than the upperA portion Y lower portion 16 of the gas Land `air mixing tube is-of'such a diameter in relation to the burner-tube 7 that between thernare formedv vthe air-spaces 18.' The gas and air mixing tube isiretained in a uniform 'position in re'- spect to tbe tube 7 by means of a series of studs or beads 19, carried-thereby and which enga ge the inner face ofthe gas and air mixing tube.`

These studs or beads extend in a vertical manner. The lower portion of the gas and air mixing tube is provided with an offset 20, forming a vertical groove 2l, extending from the lower end of the said mixing-tube to slightly above the nipple 2, and is adapted to receive the stud 12 of the plate 10. The gas and air mixing tube is loosely mounted upon the nipple 2, so it can be rotated at wil-l, and owing to the stud 12 extending in the groove 21 the stud will be carried with the tube when rotated, and consequently impart vav similar movement to the plate 10 and regulate the passage or How of the gas through the diaphragm 5, or, in other words, the plate 10 can be adj usted to any desired position by rotating the gas and air mixing tube, owing to its engagement with the stud 12. The airis not only supplied to the interior of the burnertube 7 through the openings 17 of the mixingtube and the openings 8 of the burner-tube,

but air is also supplied to the gas and air'mix ing chamber 14 through the medium of' the openings 17 and the airlspaces 18.

The reference-numeral 22 denotes a cylindrical cap which is mounted upon the diaphragm 15, the latter engaging the inner face of the depending wall of the former. The cap is of such diameter in relation to the upper portion 13 of the gas and air mixingtube as to form an independent air-passage 23v between it and the mixing-tube. The top of the cap is slitted er otherwise perforated, as at 24, to permit of the gas and air mixture from the chamber 14 and air from the passage 23 to enter within the mantle 25. The mantle is supported in a known manner and surrounds the cap 22, as shown. The gallery 26chimney 27, and globe 28 are shown in dotted lines; but any preferred form of these devices 'may be employed.

I n Fig. 4 of the drawings the burner-tube 7 isY provided with an annular bead 29 above the air-inlets 30 for limiting the introduction of air' to the burner-tube 7, as well as the mixing-chamber 14. The lower portion of the gas enlarged portion 33 of the gas andair mixing tube,which forms a mixing-chamber 14, may

be corrugated or uted, land anordinary cap 34, with a slitted or perforated top 35, may be mounted upon the enlarged portion 33 and `snugly fit the sides ofthe same, which dispenses with the'projeeting of the diaphragm and forms a series of independent air-passages 36.` The reference-numeral 37 denotes .y the mantle, adaptedto extend on the outside of the cap 3l. The regulating-platel and other parts of the device inth'is modified form are the same as hereinbefore referred to in connection with the other liguresof the drawings, the same reference-numerals being applied thereto. l

The independent air-passage 23 is provided to obtain the thorough incandescence of the mantle and greater heat in the heater by the employment of asmaller quantity of gas than employed in ,the ordinary burners. It will also prevent the accumulation of carbon upon `the mantle, for the reason that the operator cannot when regulating the burner shut oif the air, or ifv the air-inlets atthe bottom of themixing-tube should be clogged in any way the independent air-passage 23 will supply air to theburner. It will be evident that by constructing the burner -tube and mixingtube with the air-passages, as shown, the ordinary air-shutter used in devices of this character can be dispensed with. It will also be evident that owing to the arrangement of the plate 10 the supply of gas can be regulated at will from the gas-supply pipe to the burner.

IOO

By the employment of the construction of mixing-tube as shown in connection with the burner-tube the air can be mixed with the incoming gas morethan once before the latter is ignited, notl vonly through the air-inlets 8, but also through the passages 18, and as the air approaches the heat it .will more intimately unite with the gas when brought together, and it is thought that lthe many advantages lof an incandescent burner constructed in accordance with this specification, taken in connection with'the accompanying drawings, can be readily understood, and it will be noted that minor changes may be made in the de- IIO tails of-construction without departing from d the general spirit of -my invention.
